Specimen size: 2.2 × 1.9 × 1.6 cm = 0.9 × 0.7 × 0.6

Main crystal size: 0.4 × 0.3 cm = 0.2 × 0.1

Pseudobrookite

MA13AF2: Very elongated Pseudobrookite crystals with good terminations. They are bright, very well defined and are on a rhyolite matrix. An excellent miniature of a very well known American classic.
Thomas Range, Juab County, Utah USA

TD89Y3: Multiple twin of very sharp prismatic crystals. They are red, have an intense luster and are on a chloritic matrix. The sample is of great quality for the locality, relatively unknown for most collectors.The piece is from the Eric Greene collection, whose label well send to the buyer.
Davis Farm, Bethel, Windsor County, Vermont USA

TK1V2: Parallel growths of dodecahedral crystals with a deep honey color, bright and transparent. The color is darker than usual due to the size of the crystals which are unusually large for the locality, one of the great worldwide classics for the species.The sample was in the collection of John Lindell, whose label well send to the buyer.
"Mud Bunny" pocket, Vesper Peak, Sultan Basin, Sultan District, Snohomish County, Washington USA (1981)
